I temporarily removed the trap, and confirmed that it produces no picture at all with the current setup. Back on, it does make a bright picture, but only if pushed all the way back to the CRT base and rotated to the sweet spot.
I just looked back at the Riders manual, which says the focus coil should be perpendicular to the CRT axis and 1/8 inch behind the yoke. Looks like you guys might be onto something. Forehead slap. Maybe someday I'll learn to RTFM, as we used to say back when I was a technical writer.
